From the viewpoint of ED, the reason for studying this alternative formulation is largely practical: since ED deals with the dynamical evolution of \(\rho \)  and \(\Phi \) , it already largely resembles a “classical" dynamical theory. Thus a fully quantum ED will not resemble the algebraic formulation of quantum theory based on Hilbert spaces, but rather, the alternative, geometrical formulation described in [1]}-[2]}. As mentioned above, the first steps towards accomplishing this were set out in [3]}, but more work remains to be done.
